Sad day... :''(

I've made my last-time buy...

[Les Bird]

Yes I saw the end of life posting for the Z80s but I couldn't tell if it was just a certain footprint or all of them.

I usually get my 40 pin DIP Z80s (part Z84C0020PEC) from eBay, 10 for $10 - essentially an endless supply. Most of the time they are good and run at the advertised 20MHz but some just don't work at all. The first batch of 20 I ordered all worked flawlessly at 16MHz with my RomWBW H8 board but the second batch of 20 only half of them worked. Still at a $1/each it's worth the gamble.

Also, maybe it's time we move to 100MHZ FPGA Z80s...? Maybe I'll start looking into this.

There's still enough to build my 1000 node Z80 supercomputer.

I bought some at eBay. I didn’t know that Mouser had them. 👍

Yeah I’m not worried about finding any for my own personal use. Mostly I feel bad for Spencer who created the rc2014… this is going to impact his livelihood. 

Someone shared this with me… a fitting eulogy.

Availability will not be a problem for a decade or more. Even NOS Z80s made in the 1970s are still floating around in decent quantities.

Yeah, but as someone who’s first computer was an H89 in about 1986, I can’t tell you how amazing it was to want to learn more about the processor that I started out in computers with, though I never programmed it. When I wanted to revisit it as an adult, to find that there was a kit you could buy in 2018 with completely new chips was mind blowing. I went on to design my own boards for it, and I don’t think I’d be where I am today if it hadn’t been for the fact you could still buy these new from any electronics distributor. It’s going to be sad to lose that. And I still haven’t gotten the H89 I bought working, so my RC2014-derived, mostly self designed and manufactured computer is what delivers my Z80 fix. There, I guess that’s my real eulogy.

My history is similar, though a bit earlier. I understand what you mean and agree with you, and it certainly is a shame. But people everywhere are screaming that all of the Z80s in the world are going to somehow disappear, and we'll never see any again, which is simply wrong.

I don’t intend to be screaming that and I know it will be easy to find. It just feels like the end of an era.

[Dave McGuire]

I'm right there with you on that. It's a shame that the suits who made the decision, who probably don't know or care about the iconic and worshipped status of the Z80, couldn't just let it hit 50 years. It certainly deserved that, at least.

And these aren't counterfeit / fakes?

[norberto.collado koyado.com]

The same thing happened to the Z180... Now you need to use eBay to find them, especially the 33MHz ones.

No, the pdf I shared was posted directly on mouser. The parts are marked EOL on mouser. Its real.

Oh you’re asking about the chips from eBay. 😆

Anyway, these arrived today. 

[Les Bird]

Bill, hard to tell if they are counterfeit or fakes. The markings seem legit and they run everything I throw at them so bottom line is most of them work and do what they're supposed to do.

FWIW, I've noticed some of the Z80 parts have already gone out-of-stock on Mouser and Digi-key since this announcement.

There is a last lifetime buy, so they are accepting backorders.
